🕷️ Family-Owned Spider & Pest Control Services
What We Use
Spider Squad uses two Ontario government-approved professional insecticides - Suspend Polyzone and Dragnet SFR. Both are PMRA-registered, restricted to licensed operators, and proven safe for families and pets once applied surfaces are dry. Here is what each product is, when we use it, and every precaution we take.
Eight Legs Out. Family In.
Both treatments below are professional-grade products registered with Health Canada's PMRA. Applied to label, both are safe for families and pets once dry — typically 30 to 60 minutes after application.
We do not use a single product for every situation. Suspend Polyzone and Dragnet SFR have different formulations that make each one better suited to specific surfaces and conditions. Both have bifenthrin as their active ingredient - the same class of synthetic pyrethroid - but the way each is formulated determines how it bonds to surfaces, how long it lasts, and where it performs best.
Both products share the same active ingredient - bifenthrin - but the formulation technology is fundamentally different. That difference drives where and when we use each one.
The SC (Suspension Concentrate) formulation encapsulates bifenthrin particles in microscopic polymer capsules. When applied, the water carrier evaporates and the capsules bond to the surface, releasing active ingredient gradually as insects cross the treated zone. This slow-release mechanism is why Suspend Polyzone can hold residual effectiveness for 3 to 6 months outdoors - even through Ontario rain seasons.
It performs best on the smooth and semi-porous surfaces common to most residential exteriors: vinyl siding, stucco, painted wood trim, aluminum, and concrete block foundations.
The EC (Emulsifiable Concentrate) formulation dissolves bifenthrin in a petroleum-based solvent carrier that emulsifies in water. Unlike the SC formulation, the EC carrier penetrates into porous substrates rather than sitting on the surface. This penetration gives Dragnet SFR an advantage on rough, absorbent surfaces where surface-bonding SC products have limited contact area.
It is the preferred choice for waterfront docks, unfinished wood decks, log siding, split-face concrete block, and other coarse or absorptive surfaces where Suspend Polyzone's surface-bond mechanism is less effective.

Bifenthrin has low mammalian toxicity at structural pest control application rates. Both products are applied only to exterior structural surfaces and treated areas at label-compliant dilutions. Below are the precautions we observe for every treatment, without exception.
⚠️ Aquatic Caution: Bifenthrin is toxic to fish and aquatic invertebrates. Both products are applied with mandatory buffers from all water features - ponds, streams, lakefronts, and storm drains. For waterfront properties, our technicians follow enhanced buffer protocols to ensure no runoff reaches open water. This is a non-negotiable requirement under both PMRA label directions and Ontario environmental regulations.
Both products are registered with Health Canada's Pest Management Regulatory Agency (PMRA). PMRA registration is not a rubber stamp - it requires the manufacturer to submit data packages covering toxicology, environmental fate, efficacy, and residue chemistry. Health Canada reviews this data and approves the product only if it meets Canadian safety and performance standards.
PMRA registration also restricts use to licensed operators in the case of structural pest control products like Suspend Polyzone and Dragnet SFR. This restriction exists because application rate, dilution, and site selection all require professional training to execute safely and legally.
When a Spider Squad technician applies either product to your property, they are operating under their Ontario pesticide applicator licence, within PMRA label parameters, and in compliance with all applicable provincial regulations. There are no shortcuts taken, no off-label applications, and no substitutions.
Why do you use two products instead of one?
Different formulations perform better on different surfaces. Suspend Polyzone's SC formulation bonds exceptionally well to smooth and painted surfaces common on most homes. Dragnet SFR's EC formulation penetrates porous materials like raw wood and rough concrete more effectively. Using the right product for the surface type means better residual performance and more complete coverage.
Are both products safe for children and pets?
Yes - once applied surfaces have dried, which takes approximately 30 to 60 minutes. Bifenthrin has low mammalian toxicity at structural pest control exposure levels. Both products are PMRA-registered and applied by licensed operators at approved label rates. Residents are asked to stay away from the treatment area during application and until surfaces are dry.
Can I request a specific product?
Yes. If you have questions about which product your technician is using or want to confirm the product before booking, call us at 905-935-7498. Your technician will also confirm what product is being applied before starting work and can provide the SDS on request.
Do you use any other products besides these two?
Our standard exterior spider and insect control program uses Suspend Polyzone and Dragnet SFR. For mosquito and tick treatments, we use products registered specifically for those applications. All products we use are PMRA-registered and applied according to label directions by licensed operators.
Can I see the Safety Data Sheet for the product being applied?
Absolutely. Our technicians carry printed SDS for every product in their vehicle. Request a copy before, during, or after your treatment. You can also ask us to email the SDS prior to your appointment. We do not use any product we are not fully prepared to discuss and document.
What is bifenthrin?
Bifenthrin is a synthetic pyrethroid insecticide - a class of chemicals modelled on pyrethrins found in chrysanthemum flowers but engineered for greater stability and residual effectiveness. It works by disrupting voltage-gated sodium channels in insect nerve cells, causing hyperexcitation and paralysis. It has low toxicity to mammals at structural pest control application rates and is widely used in licensed pest control across North America.
